The part of the brain which is connected to spinal cord is

Options

A. Pons
B. Cerebellum
C. Hippocampus
D. Medulla oblongata

Answer

To answer the question, "The part of the brain which is connected to the spinal cord is," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Central Nervous System (CNS)**:
- The CNS is composed of two main parts: the brain and the spinal cord. The brain is responsible for processing information and controlling bodily functions, while the spinal cord acts as a conduit for signals between the brain and the rest of the body.

**Hint**: Remember that the CNS includes both the brain and spinal cord.

2. **Identifying Brain Structures**:
- The brain is divided into several parts, including the cerebrum, cerebellum, and brainstem. The brainstem itself consists of the midbrain, pons, and medulla oblongata.

**Hint**: Familiarize yourself with the main parts of the brain and their functions.

3. **Locating the Connection Point**:
- The spinal cord connects to the brain at the brainstem. The brainstem is crucial as it controls many involuntary functions and acts as a relay between the brain and spinal cord.

**Hint**: Focus on the brainstem as the key area where the brain connects to the spinal cord.

4. **Identifying Specific Parts of the Brainstem**:
- Within the brainstem, the three main parts are:
- **Midbrain**: Located at the top of the brainstem.
- **Pons**: Positioned in the middle, it acts as a bridge between different parts of the nervous system.
- **Medulla Oblongata**: Located at the bottom, it controls vital functions such as heart rate and breathing.

**Hint**: Remember the order of the brainstem parts: midbrain (top), pons (middle), and medulla oblongata (bottom).

5. **Determining the Correct Answer**:
- Among the options given (pons, cerebellum, hippocampus, medulla oblongata), the **pons** is the part of the brain that serves as a connection between the brain and the spinal cord.

**Hint**: Eliminate options that do not serve as a connection point (like cerebellum and hippocampus).

### Final Answer:
The part of the brain which is connected to the spinal cord is the **pons**.
